Optical instruments often fog up during the night. Eyepieces, lenses, and Schmidt plates: when a fine layer of mist settles on your optical instruments, the observing night is over. But this doesn't have to be the case. Omegon heat strips for dew shields keep moisture away and guarantee you a super sharp view all night long.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdvantages at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe heated sleeve keeps your telescope, finder scope and eyepieces free of fog.\u003c\/li\u003e\n\u003cli\u003eEasy adjustment: flexible strap for a perfect fit.\u003c\/li\u003e\n\u003cli\u003eVelcro fastener: attaches anywhere on the top of the heated sleeve.\u003c\/li\u003e\n\u003cli\u003eUSB plug with 2-metre long cable.\u003c\/li\u003e\n\u003cli\u003eAvailable for different tube sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eWhy do your optics fog up?\u003c\/b\u003e\u003cbr\u003eAnyone who wears glasses knows very well the effects of dew on an optical surface. When entering a warm room from the cold. Suddenly, a fine mist of water droplets settles on your glasses because warm air condenses on the cold glass surfaces. Exactly the same happens to the lenses of your telescopic optics. When your optics cool down, condensed water settles on the surface. It's time to see clearly!\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCompact and always at hand\u003c\/b\u003e\u003cbr\u003eSimply practical: just roll the sleeve around the optical tube or eyepiece at the beginning of your observation session. It fits like a glove and is secured by means of a self-adhesive fastener. And, when you've finished exploring the sky, simply store it back in your eyepiece case. This way you'll always have the telescope heating at hand, for a clean optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKeeps your optics fog-free\u003c\/b\u003e\u003cbr\u003eJust connect the cable with USB plug to a suitable power source:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 40 cm in length, the heated sleeve comes with a USB-A plug. A small power bank or a standard USB power source that supports fast charging is sufficient. (Do not connect the USB-A plug to a computer, as in some cases its USB port could be overloaded).\u003c\/li\u003e\n\u003cli\u003eFrom 50 cm in length, the heated sleeve has a USB-C plug. It requires 12 volts, which is what most USB power supplies with Power Delivery (USB-PD) supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTip: If your power bank has a cigarette lighter connection, you can use the [cms:\/\/shop\/p_id=83093 \"\"] to connect additional USB ports.\u003c\/p\u003e\n\u003cp\u003eThe direct current distributes the power evenly throughout the band at only 0.2 watts per centimetre. What this means for you: Your heated sleeve effectively maintains the temperature a few degrees above the outside temperature. Dew no longer has a chance. In addition, its power consumption is minimal and therefore does not harm your batteries.\u003c\/p\u003e\n\u003cp\u003eOmegon dew shield heat strips offer you more viewing pleasure for longer. When other stargazers have already packed up their telescopes, you can observe for as long as you wish.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOther highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e20 mm wide heating element inside\u003c\/li\u003e\n\u003cli\u003eStrap width: 44 mm\u003c\/li\u003e\n\u003cli\u003eColour: black exterior\/red interior\u003c\/li\u003e\n\u003cli\u003eMaterial: Cordura\/nylon\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eContents:\u003c\/p\u003e\n\u003cp\u003eHeated sleeve with cable and USB plug\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581619429719,"sku":"58022","price":99.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/58022_1.jpg?v=1779016746","url":"https:\/\/astrotelescopios.com\/en-eu\/products\/manguito-calefactado-fogfree-usb-40cm","provider":"Astro Telescopios","version":"1.0","type":"link"}
